WINDIVIILL.

SPECIFICATION forming part of Letters Patent No. 628,412, dated July 4,1899. 4 Application tiledNcvemher 2, 1898. Serial No. 695,267. (Nomodel.) i

To all w/Lom it may concern:

Be it known that I, JOHN MUIR, a citizen of the Dominion of Canada,residing at Brantford, yin the Province of Ontario, Dominion of Canada,have invented certain new and useful Improvements in Windmills; and I dohereby declare the following 'to be a full, clear, and exact descriptionof the invention, sueh as will enable others skilled in the art to whichitappertains to make and use the same.

The invention relates particularly to such windmills as drive a pump-rodor other reciprocating part. In mills of this kind the wind-wheel shaftis usually provided with a crank and pitman, and as this constructioninvolves great strain and wear in the wind` mill-head, which is noteasily reached nor readily repaired when reached, owing to constructionand for other reasons deemed necessary, many devices have been used tolessen the evils suggested.

The object of this invention is to eliminate the evils completely, andthis object is attained by placing the crank and pitman in' the towerbelowand providing means whereby they may be driven by the latterwithout the usual lateral strains.

In the accompanying drawings, Figure `l shows the head'and the upperportion of the tower of a windmill provided with my devices. Fig. 2 is adetail View showing parts as seen when looking in the direction of thearrow of Fig. l.

In the figures, A represents a steel tower having a cap B, supporting aturn-table B. Far below this turn-table and within the tower is a secondand parallelturn-table G, consisting of a iianged and braced horizontalring litting within and upon a ring H or equivalent bearings attached tothe contiguous posts of the tower. The two turn-tables,l

are connected by members F F', extending downward from the head proper,O, and forming with the turn-tables one rigid structure, which supportsabove the tower the usual wind-wheel spider and shaft D E and vane D.

vBelow the lower table is a shaft K, parallel nearly in the verticalaxis of the mill. A belt or chain Lconn'ects the two pulleys, andpreferably the pulleys lie in a plane perpendicular to the plane of themembers F F and mid' way between them. The lower pulley bears awrist-pin N, and to this is attached a pitman to be connected with apump-rod or the like. This greatly-elongated head supported by the twowidely-separated turn-tables holds the mill with steadiness andsecurity, and the thrust of the pitman is borne by parts located wherethere is ample space for strong construct-ion, where the parts aresupported on all sides ,by the tower-posts, and where they are readilyaccessible without dangerous exposure upon the topof a tower and in aplane swept by shifting wheel and vane.

It is obvious that the lower pulley may be above the ring and that itsdistance from the I forth may be varied in other respects withoutpassing the proper limits of my invention.

What I claim isl. The combination with the tower and the turn-table uponits top, of a turn-table mounted within the tower at some distance belowits top, the head members extending down through both turn-tables andrigidly connecting them, the wind-wheel shaft mounted above the tower,the parallel shaft supported by said members near the lower turn-table,pulleys fixed upon the shafts, respectively, vin the same plane, a beltconnecting the pulleys, and a pitman carried by the lower pulley.

2. The combination with the tower and its cap, of the ring within thetower and xed to its posts at some distance below its top, theturn-table above the cap, the turn-table supported in said ring, thehead having members forming with the two turn-tables a rigid rotarystructure, a wind-wheel shaft in the head above the tower, a parallelshaft mounted in said structure near thelower turn-table, pulleys in thesame plane upon the two shafts, respectively, a belt connecting thepulleys and a pitman carried by the lower pulley.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN MUIR.
